Concrete

Concrete is currently the most widely used and used building material in the world. It plays an irreplaceable role in the construction of construction engineering, highway engineering, bridge and tunnel engineering, water conservancy and special structure construction. Any concrete structure is mainly used to bear load or resist various forces. Strength is the most important mechanical property of concrete.

Concrete refers to a collective term for engineering composite materials in which aggregates are cemented into a whole by cementitious materials. The term concrete usually refers to cement concrete that uses cement as a cementing material and sand and stone as aggregates; it is mixed with water (which may contain admixtures) in a certain proportion and is mixed by a concrete mixer. It is also called ordinary concrete, it is widely used in civil engineering.
